Hi there,This is Dr Basu, Experienced Specialist.I am here to address your concerns and provide great service.No they will not show up in 5 panel drug test.Percocet and hydrocodone are both synthetic opiates.In 5 panel drug test, only morphine, codeine and heroin are detectable.Percocet or hydrocodone are not metabolized into these compounds.So they will not be detectable.Best wishes,It was my pleasure to help you today.If I have answered all your questions, Please click on Excellent service so that the website allows me to assist you further :)

HiI am a medical review officer trained in the interpretation of drug testing If you have prescriptions for these medications, it doesn't matter if you test positive, because they will be excused But in general, synthetic opiates are not tested for with the 5 panel test- and that includes the medication you are asking about I hope this helped Please leave positive feedback for my time and expertise :-)
